100х²-20х+1=(10х-1)²
1-20х+100х²=(1-10х)²
100х²-20х+1=0
х1,2=(10+/-√100-100)/100
х1=х2=10/100=1/10
х1=1/10 х2=1/10

Living in a city
Living in a city has both advantages and disadvantages. On the plus side, it is often easier to find job, and there is usually a choice of public transport, so you don’t need to own a car. Also, there are a lot of interesting things to A____ and places to see. For example, you can eat in good restaurants, visit museums, and go to the theatre and to concerts. What is more, when you want to relax, you can usually find a park where you can B____ the ducks or just sit on a park bench and read a book. All in all, city life is full of bustle and variety and you need never feel really bored.

However, for every plus there is a minus.

In conclusion, I think city life can be particularly appealing to young people, who like the excitement of the city and don’t mind the noise and pollution. However, many people, when they get older, and particularly when they have young children, often prefer the peace and fresh air of the countryside.
